i) Researchers studying a population of tiger puppies identified a recessive single gene allele causing albino tiger puppies. In the population they were studying they identified 26 albino tiger puppies out of 6000 total tiger puppies. What is the predicted number of carriers in this population for this trait.

ii) You sample 100 one-child families in which the mother is heterozygous for genes AB and C and the father is homozygous recessive for genes ABC and the offspring have the following phenotypes

ABC – 29, ABc - 12, AbC – 2, aBC – 7, abC – 9, aBc – 2, Abc – 9, abc – 30

What does this tell you about the relative location of these genes on the chromosome?

iii) How long in weeks does it take to make a CRISPR mutant?

In a snail, an autosomal allele causing a banded shell (b) is recessive to the allele for unbanded shell (B). Genes at a different locus on the same chromosome determine the background color of the shell; here, yellow (y) is recessive to brown (Y). The genes for shell banding and background color have a recombination frequency of 0.25. A banded, yellow snail is crossed with a homozygous brown, unbanded snail. The F1 are then crossed with banded, yellow snails (a...

The black color cost in hamsters is due to a dominant gene (B).. A recessive allele (b) at this locus results in a brown coat when homozygous (b/b). However, neither coat color is expressed when the organism is homozygous for the allele (a) at a separate locus. The a/a genotype results in a white (albino) coat, regardless of the allele at the B locus. The wild-type allele (+) at the (a) locus allows normal coat coloration, whether the genotype is...

In Drosophila, the recessive dp allele of the dumpy gene produces short, curved wings, while the recessive allele bw of the brown gene causes brown eyes. In a testcross using females heterozygous for both of these genes, the following results were obtained: wild-type wings, wild-type eyes 178 wild-type wings, brown eyes 185 dumpy wings, wild-type eyes 172 dumpy wings, brown eyes 181 In a testcross using males heterozygous for both of these genes, a different set of results was obtained:...

Cystic fibrosis is caused by a mutation in a single gene. Homozygotes for this mutant recessive allele (ff) have cystic fibrosis. Within a population, 2% of people have cystic fibrosis. Assuming Hardy-Weinberg equilibrium, the frequency of heterozygotes in the population is 0.24. If inbreeding was common in this population, what would happen to the percentage of people who have cystic fibrosis over time?
